Title: Estimating method for temperature of nitrogen oxide trap arranged in exhaust passage of engine
Inventor: CULLEN MICHAEL JOHN
IPC: F01N13/02
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To suppress the damage of an NOx trap by obtaining the estimation before a sensor output, the instantaneous temperature of the trap, and the tem perature change rate of a sensor, estimating the temperature of the NOx trap arranged on the downstream side from a ternary catalyst converter, and control ling the temperature of the trap. SOLUTION: The exhaust gas guided into a ternary catalyst converter 26 from an exhaust system 22 and applied with a catalytic action is fed to an NOx trap including two separated bricks 30a, 30b. A heated exhaust gas oxygen (HEGO) sensor 32 is arranged between two bricks 30a, 30b, and its sensor signal is inputted to an EEC20 together with the output signals of HEGO sensors 38, 40 and a mass air flow sensor 50 arranged on the upstream and downstream side of a trap 30. The temperature outputs of the sensors are estimated based on the prescribed temperature change rate, a trap temperature correction term is learned based on the temperature error between the estimated sensor outputs and the actual outputs of the sensors, and the trap temperature is corrected.

Abstract: PROBLEM TO BE SOLVED: To increase the torque efficiency and the shift feeling by converting one of a speed steep of a first, second, a third and a fourth speed between a high and a low speed with a scanned shift gear mechanism so as to increase the number of shift steps. SOLUTION: At a first speed in a 'D' range, for example, a third and a fifth friction elements C2, B2 of a first shift gear mechanism 17 and a first one-way clutch F1 are operated, and a sun gear 21 is operated at an input step, and an epicyclic carrier 29 is operated at a fixed step, and the sun gear 19 is idly rotated so that a vehicle is operated at primary first speed.

Title: Torque converter
Inventor: SAKAMOTO HARUO
IPC: F16H41/26
Filed: 1990-09-18
Abstract: PURPOSE:To balance centrifugal force in the blade width direction with a pressure gradient so as to secure the high performance of a converter by setting the angular distribution on the blade width in a turbine blade to the force vortex distribution, and also setting the angular distribution on an average flow line in such a way as to have the maximum angular change at the blade center part. CONSTITUTION:The angular distribution on blade width in a turbine blade 2c is set to the free vortex distribution, and the angular distribution on an average flow line AL in the turbine blade 2c is set in such a way that the torque momentus becomes the maximum at the blade center part. An offset angle theta, formed by a y-axis and a straight line connecting the origin of an x-y coordinate of the y-axis passing the shell-shape entrance side end to the core-shape entrance side end, is set within a range of -3 deg.--7 deg.. The shape of the turbine blade is thus set appropriately in such a way that the centrifugal force in the blade width direction in the turbine blade is balanced with the pressure gradient. As a result, the turbulence of flow around the blade can be suppressed to a minimum, and thus the performance of a converter is improved.

Title: Electrophotographic printer
Inventor: YAMAMOTO SATOSHI
IPC: G03G15/36
Filed: 1987-10-05
Abstract: PURPOSE:To obtain a printer having high printing throughput without shortening the life of a photosensitive drum, by stopping the rotation of the photosensitive drum when there is no next page printing and continuing said rotation when there is the next page printing. CONSTITUTION:A printing control part 23 applies a certain value to a variable timer 24 when the printing of the first page is finished and waits until the printing start order of the next page is emitted from a main control part 12 while the photosensitive drum 1 is rotated during this time. When the printing start order is emitted within the time, printing is rapidly performed but, when there is no order within the time, the main control part 12 refers to flags 17, 18 to judge whether the video data of the next page is present with respect to respective data buffers 15, 15 and transmits the judge result to the printing control part 23. The printing control part 23 stops the photosensitive drum 1 when there is no data and resets the variable timer 24 when there is the data to wait the printing start order of the next page while rotates the photosensitive drum 1.

Title: Antifouling coating composition
Inventor: TAKIYAMA EIICHIRO
IPC: C09D5/14
Filed: 1989-09-26
Abstract: PURPOSE:To obtain an antifouling coating compsn. exhibiting excellent coating film characteristics such as an antifouling effect for a long time by using both of a polymer having a functional group reactive with an inorg. copper compd. and a kneaded mixture of a specified resin or a fatty acid with an inorg. copper compd. CONSTITUTION:An antifouling coating compsn. comprising a polymer (a) having one or more functional groups reactive with an inorg. copper compd. and a kneaded mixture (b) of a resin with a mol.wt. of 3,000 or lower and one carboxyl group in its molecule or a fatty acid with an inorg. copper compd. The reason why the mol.wt. is restricted to 3,000 or below is that a mol.wt. where a limitation in compatibility with the polymer occurs is close to this value and, though it depends on the structure, a higher mol.wt. results in impairing its stabilizing effect when the kneaded mixture with copper suboxide is incorporated in the polymer. The most desirable mol.wt. of an oligomer with one carboxyl group is 200-1,500.

Title: Removing method of oxygen dissolved in water and its composition
Inventor: MORIYAMA HITOSHI
IPC: C02F1/58
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To increase the effect to remove oxygen and its safeness by allowing a compsn. containing gallic acid esters and alcohols to be present in water. SOLUTION: As for the gallic acid esters, alkyl esters having 1 to 12 carbon atoms of gallic acid are used. As for alcohols to dissolve the gallic acid esters, 1 to 3-valent alcohols having 2 to 4 carbon atoms are used. The proportion of alcohols to gallic acid esters is properly determined as far as the alcohols can dissolve the gallic acid and the soln. can be uniformly dispersed in the objective water, and alcohols about 2 to 5 times by weight as the gallic acid esters are used. To remove oxygen dissolved in water, the compsn. above described is added to the objective water to uniformly dissolve the gallic acid esters. The amt. of the compsn. to be added is controlled so that 2 to 5 mol. of gallic acid esters are added to 1 mol. of oxygen dissolved in water.  When the compsn. is added to a boiler water system, its amt. is controlled so that about 0.01 to 200 mg of gallic acid esters are added to 1 L of the water fed to the boiler.

Title: Belt-type centrifugal force column manufacturing machine and form therefor
Inventor: ISHIKAWA KOICHI
IPC: B28B21/80
Filed: 1991-09-03
Abstract: PURPOSE:To eliminate a movement of a form in the axial direction and to make it possible to manufacture stably a column by putting a belt on pullies with an approximately drum shape projecting to the outer periphery from the end face to the width center and putting the form provided with a tire having the same shape as that of the pulley on the belt. CONSTITUTION:A belt 8 is hanged on pullies 5-7 and a cylindrical form 9 is placed on the belt 8 on a pair of main pullies 5 and 6. The pullies 5-7 have respectively a horizontal part W1 being parallel to the axial direction on its central part and continuously have an inclined part wherein the diameter is gradually decreased toward the side end. A belt has a property approaching toward a higher position so that the belt always comes to a condition wherein it is hanged on the horizontal part W1. Several tires 12 each with a width being wider than that of the belt 8 are formed on the form 9 and the shape is made approximately the same as those of the pullies 5-7. By making the shapes of the pullies 5-7 and the tire 12 to be approximately drum shape, the crosssectional shape of the belt becomes concave downward on the pulley and concave upward to make holding of the form strong and to prevent as much as possible the form from transverse movement.
